Answer:
aluminum is highly reactive
Answer:
Helium
Explanation: The real gas that acts most like an ideal gas is helium. This is because helium, unlike most gases, exists as a single atom, which makes the van der Waals dispersion forces as low as possible. Another factor is that helium, like other noble gases, has a completely filled outer electron shell.
A. Filtration
This is because of the layers of Filter it goes through to make sure it is pure.
The question is incomplete, the complete question is;
The levels of organizations in multicellular organisms are shown below, but they are not in the correct order. Arrange the levels of organization in order from simplest to most complex. tissues organs whole organisms organ systems
Answer:
tissues --> organs --> organ system --> whole organisms
Explanation:
The levels of organizations in multicellular organisms refers to the increasing complexity of the components of the organism.
A tissue is an aggregation of cells hence it is the lowest level of organization here.
Organs are an aggregation of tissues, this is the next higher level of organization.
Organ systems are an aggregation of organs, this is the next higher level of organization.
Whole organisms are an aggregation of organ systems. This is the highest level of organization.
Answer:
kilograms of sulfur will be emitted from coal plants in two weeks
Explanation:
Power produced by power plants in the United States :P
P=
1 Joule = Watts × Seconds
Watts = Joule/Second
P=
This means that Joules of enrgy is produced in one second.
So, energy produced in 2 week:
1 week = 7 days
1 day = 24 hours
1 hour = 3600 seconds
2 week = 2 × 7 × 24 × 3600 s=1,209,600 s
Energy produced in 1,209,600 s: E
Coal has an energy content =
Mass of coal used while producing E amount of energy: m
Percentage of sulfur in coal = 4% by mass
Mass of sulfur produced from in 2 weeks:
